cured in position by means of bolts 25, which serve also to'secure the running board saddles (not shown) imposition. f

The inverted channel-shaped ridge sean covers 22 are narrowest at'the middle and gradually increase inl width towards each end. The surplus metal resulting. from the decreased width of the middle portions of the ridgeseain covers is pressed up, on oppo site sides of their longitudinal center lines, to forin'V two laterally spaced longitudi nallyV extending hollow ribs or invertedy seam covers changes gradually from a single inverted channel at each end to a section at the middle comprising two laterally spaced inverted channels.As lshown in the drawing, the ridge seam covers, together with the ribs or grooves thereon, are made widest VV*at'the ends by curving theirzopposite side walls in opposite directions away from each other; but it is noted that this widening or vflaring of said ridge seam covers and said ribs may also be produced with straight side walls that diverge from each Vother from the middle of the covers towards their ends.

.being pitched The Vridge seam flanges 15 of the` roofi sheets are of a width corresponding substantially to the width of the narrow middle vportions of the downwardly opening longitudinal grooves formed by the hollow ribs 26 on the .tops of the ridge seam covers,n

and said ridge flanges; have a maximum height midway of their ends and gradually decrease in heighty towards the side flanges thev tops of the ridge flanges of the sheets,

at substantially the same in# clination as the tops of said hollow ribs By thearra-ngement described, the hollow ribs of the ridge seamV covers areiadapted Vto closely embrace the ridge seam flanges disposed roof sheets at theV middle oftheridge; ends thereof and thus ymaintain a of said sheets aswell 'as preventing indeof oppositely proper spacing of the ridgeends pendent or Ajoint bodily movement thereof cross-wise vof the car. double Y,convexityV of the grooves'forined by the ribs, closely embrace the ridge fianges of the roof sheets at the lmiddle of the ridge ends andV arespaced therefrom at the sides'of the sheets, whereby said sheets are forcedy toV rock or roll aboutY the Aci'j'ntacting portions of the ridge seam covers during the rackingrk By lreason ofqthe side walls of theV said seam capsY sides closely embrace and weaving of the car frame and lthus ac-v the j distortions injury to the metal; it greatly increases the strength kand rigidity of. the seamV covers and thus prevents said Covers from becomingbent, twisted or crushed and interfer-` ing with vor preventingthe desired sluing movement of the sheetsyandit is of simple and compact design andcan be produced with great economy. v

What I claim is: y

2. A flexible car roof comprising movably mounted roof sheets spaced apart along their adjacent margins andv having raised portions extending along said margins, andv a seam cover secured to the ycar andV covering the raised portions of adjacent sheets, said seam cover being provided with downwardly opening longitudinal grooves that straddle said raised lportion, and have contact with both sides thereof for a portion Vof their itil) length only, said grooves being formedv in l the top of said seamcover.`

3. A flexible car roof comprising movablyV mounted roof sheets spaced apart along their adjacent margins and having raised :portions extending along said margins, and a seam cover secured to thegcarfand covering Y the raised portions of adjacent sheets, the.'

and a seam cover secured to the carV and covering said upstandmg seam flanges, sald seam cover being of substantially invertedv channel-shaped section and having hollow laterally 'spaced llongitudinal ribs in its top that are deepest and narrowest at the middle portion of the seam cover and gradually decrease in depth and increase in width to-lL wards its ends where they merge into the.

plane of the top of said cover, saidribs straddling said seamv 'flanges whose top portions slope downwardly from their middle towards their ends to correspond substantially tov the slope of said ribs.

6. VA flexible. car roof comprising movably `mounted roof sheets spaced apart along their adjacent margins and having upstanding seam flanges extending lengthwise thereof that have a maximum depth at their middle and gradually decrease in' depth to their ends, and a seam cover covering the `seam flanges at the adjacent marginsy of saidy sheets, said seam coverhaving a minimum width at its middle and gradually increasnels in its top that fit over the adj acentseamV flanges, said channels being narrowest and deepest at the Vmiddle of said seam cover and gradually increasing 1n width and increasing in depth toward the ends thereof.
